Over Post+ – Zirconia Glass Fiber Post

The innovative fiber post with AAS (Active Adhesion System), the biomimetic matrix-integrated bonding principle of Over Post+, to increase the adhesion with OverCEM SA Self-Adhesive luting cement through a tested chemical interaction.

Over Post+ are glass fiber posts with conical-cylindrical shape.
As Overfibers post surfaces are particularly rough the silanization treatments are an optional.

Clinical Directions

Over Post+ are specific for teeth with missing or massively destroyed crowns as they present the maximum emergency diameter at the level where they come out of the root, according to the most recent studies regarding the root canal shapes of the teeth treated endodontically.

Their special quality is having a large emergency coronal diameter compared to the relatively small apical diameter: this design stabilizes the prosthetic core much more effectively, making the restoration more resistant to the displacing forces of mastication.

Features Advantages
Active Adhesion System to SA/SE Cements Chemical interaction with SA/SE Cements
Highly retentive surface Increases the post / cement adhesion without weakening it with deep grooves
Zirconia glass fiber 80% high flexure strength 1650 MPa
Balanced flexure E-modulus 60 GPa to better stabilize the restoration
Translucent provides esthetics and light transmission
Radiopacity 3.0 mm or 300% Al equivalent
Fatigue Strength 5 Millions Cycles Without Breaking
Sterilization in autoclave 135°C at 2.1 bar for 5 min without any variation of their resistance

Over Post+ and Prosthetic Drill are available in four sizes, with color coding for a corresponding use.
